The bike race in which thousands of cyclists are riding from London to Surrey has been shortened by 14 miles amid a forecast of heavy rain.
Organisers of RideLondon said they "reluctantly" made the decision to cut the race from 100 miles to 86 after information from the Met Office as the effects of Hurricane Bertha's remnants are felt in the UK.
The route will now miss out a section covering Leith Hill and Box Hill in Surrey due to predictions of heavy rain.
More than 22,000 amateur riders are taking part in the race, which finishes on the Mall outside Buckingham Palace.
The professional riders head out from the Olympic park in east London at 1pm.

The sun has been shining on the hundreds of cycling enthusiasts taking part in RideLondon 2014. Today's events included a fun ride around central London and an attempt to break the world record for the world's biggest bicycle bell ensemble.

Olympian Laura Trott was one of 639 cyclists bidding for the World Record in front of the Guildhall in the City of London this morning. Led by bell-ringing musicians from the Guildhall School of Music, they surpassed the total of 503 cycling bell-ringers set in 2003 by the University of Leipzig in Germany, in front of officials from the Guinness Book of Records.

Miss Trott, 22, who is racing later today in the grand prix event, said it had been worth getting up early for what is her second world record.

The Essex-born champion added: "For me when I was growing up there was never really those opportunities - they would never shut down a whole city. For cycling to have come that far and be able to do that is incredible."

The orchestra was conducted by Guildhall School of Music's Dominic Wheeler, who was working with bike bells for the first time in his career to perform a specially composed variation on the Westminster Chimes.

Miss Trott and Olympic and Tour de France star Sir Bradley Wiggins will take part tomorrow in a 100-mile road race which ends on The Mall.
